Document Type and Number:
Japanese Patent JP2006503354
Kind Code:
A
Abstract:
A field instrument and system for obtaining pressure, flow and temperature data from a facility. The field instrument includes an enclosure having an opening therein. An integrated analog sensor is sealingly contained within the opening. The field instrument further contains an external analog sensor. An analog to digital converter converts the analog signals to digital readings. An external digital sensor is also provided, with the digital output being communicated through a second opening within the enclosure. A control member that receives, stores and processes the digital readings is positioned within the enclosure. A communication module is included to transmit the digital readings to a remote computer. The communication module allows for two way communication between the field instrument and remote computer. The remote computer may be a server that allows for access by many users. The communication module also allows for locally accessing the digital readings via a serial port to a local terminal.
